The document is organized by the type of data collected. General Notes: There are five folders containing data for the five different techniques used: NMR, SEC, DSC, SAXS, and rheology (with a subfolder for shift factors). The table below shows how the samples have been named in the data files contained, where "z" refers to grafting density. The first column shows how the samples are labeled in the data files contained here, the second column shows how the samples are labeled in the supporting information. Additional characteristics of each sample are available in the supporting information associated with the published manuscript (https://dx.doi.org/10.1021/acsmacrolett.8b00116). A series corresponds to z = 1.0 polymers B series corresponds to z = 0.15 polymers C series corresponds to z = 0.05 polymers D series corresponds to z = 0.25 polymers E series corresponds to z = 0 polymers F series corresponds to z = 0.50 polymers G series corresponds to z = 0.20 polymers H series corresponds to z = 0.40 polymers A1 (PLA)12 A2 (PLA)24 A3 (PLA)55 A4 (PLA)97 A5 (PLA)200 A6 (PLA)510 A7 (PLA)1100 A8 (PLA)2900 B1 (PLA0.15-ran-DME0.85)88 B2 (PLA0.15-ran-DME0.85)170 B3 (PLA0.15-ran-DME0.85)420 B4 (PLA0.15-ran-DME0.85)720 B5 (PLA0.15-ran-DME0.85)1500 C1 (PLA0.05-ran-DME0.95)200 C2 (PLA0.05-ran-DME0.95)410 C3 (PLA0.05-ran-DME0.95)950 D1 (PLA0.25-ran-DME0.75)40 D2 (PLA0.25-ran-DME0.75)88 D3 (PLA0.25-ran-DME0.75)210 D4 (PLA0.25-ran-DME0.75)410 D5 (PLA0.25-ran-DME0.75)840 D6 (PLA0.25-ran-DME0.75)1800 D7 (PLA0.25-ran-DME0.75)62 D8 (PLA0.25-ran-DME0.75)130 D9 (PLA0.25-ran-DME0.75)270 D10 (PLA0.25-ran-DME0.75)330 D11 (PLA0.25-ran-DME0.75)640 D12 (PLA0.25-ran-DME0.75)1500 E1 (DME)100 E2 (DME)200 E3 (DME)510 E4 (DME)900 F1 (PLA0.5-ran-DME0.5)22 F2 (PLA0.5-ran-DME0.5)85 F3 (PLA0.5-ran-DME0.5)460 F4 (PLA0.5-ran-DME0.5)960 F5 (PLA0.5-ran-DME0.5)2600 G1 (PLA0.2-ran-DME0.8)120 G2 (PLA0.2-ran-DME0.8)1100 H1 (PLA0.4-ran-DME0.6)440 H2 (PLA0.4-ran-DME0.6)1600 Files Contained: Additional information about the preparation of each series of data can be found in the supporting information associated with the manuscript. NMR data: nuclear magnetic resonance (NMR) spectroscopy data for each sample has its own separate data folder, labeled with the sample name (the A series and E series were not studied by NMR). In each folder is the data as downloaded from the instrument. The .fid file can be opened in any NMR analysis software (e.g. MNOVA or iNMR). SEC data: size exclusion chromatography (SEC) data for each series has its own separate data file, labeled with the series name. Each sample's data is output in two columns where the sample name is listed in the first row. The first column shows the elution time in minutes and the second column shows the differential refractive index (dRI) signal, with arbitrary units. All data is saved as a .csv file. SEC data were collected using two Agilent PLgel MIXED-B 300 × 7.5 mm columns with 10 µm beads, connected to an Agilent 1260 Series pump, a Wyatt 18-angle DAWN HELEOS light scattering detector, and Optilab rEX differential refractive index detector. The mobile phase was tetrahydrofuran. DSC data: differential scanning calorimetry (DSC) data for each sample has its own separate data file, labeled with the sample name. The data starts on line 64, with the column headings listed in rows 46-51. All data is saved as .txt file. DSC data were collected using a TA Q1000 equipped with a TA LNCS under dry N2. The data reported was collected on the second heating cycle. SAXS data: small angle x-ray scattering (SAXS) data for each sample has its own separate data file, labeled with the sample name (the following samples were not characterized by SAXS: A8, E1, E2, E3, G1, G2, H1, and H2). "q" is a wave vector, inversely related to the scattering angle with units of angstroms, "A", and "I" is the intensity with arbitrary units. All data is saved as .txt file. All SAXS data were collected at the Sector 5-ID-D Dow-Northwestern-Dupont beamline (Advanced Photon Source at Argonne National Laboratory). Rheology data: the time-temperature superposition (TTS) shifted data for each sample has its own separate data file, labeled with the sample name. The subfolder contains the shift factors used to shift the data for TTS for each individual sample, labeled with the sample name. For the primary Rheology data files, G' is the storage modulus, G" is the loss modulus, G* is the complex modulus, eta* is the complex viscosity, and T is the temperature in degrees Celsius. All data is saved as .csv file. All rheology data was collected using a Rheometric Scientific Ares 2 rheometer with temperature controlled by a forced convection oven. Are there multiple versions of the dataset? N Description of methods used for collection, generation, and processing of data: Additional supporting information, including documentation on the synthesis of model materials, is located with the published manuscript. People involved with sample collection, processing, analysis and/or submission: Alice B. Chang and Tzu-Pin Lin collected all NMR and SEC data. Ingrid N. Haugan and Michael J. Maher collected all rheology and DSC data. Ingrid N. Haugan collected all SAXS data.
